Here is a great indicator that was made by Mladen as well which can be added to our Adaptive Indicators thread - The PA (Phase Accumulation) Adaptive Bollinger Bands with Multiple Deviations for MT4.

Apologies if there is a version of this already but I couldn't find this one on our site so I'll post it here. Hopefully someone will find it useful for their own trading as it works well for forecasting Volatiliy and breakouts as well as counter-trend trading.

As explained by Mladen:
PA adaptive Bollinger bands ...

This is a phase adaptive Bollinger bands with a possibility to draw up to 3 Bollinger bands. Thought that phase adapting would be convenient for this since it looks for cycles and it is similar in basic idea to what Bollinger bands are looking for too
